To all whom it may concern,.-

Beit known that I, Virus SCHWANINGER, a subject of the Emperor of Germany, residing and having my post-office address at Oggersheim,nearMannheim,Ger1nany,have invented certain new and useful Improvements in Apparatus for Raising Liquids, of which th following is a specification.

In apparatus for raising liquids by means of steam or compressed air, in which the alternate opening and closing of the steam or compressed-air valve are eected by means of a double-bodied float, the upper and lower parts of which are connected by a rod on which they are adjustable, the quantity of liquid to be raised during each stroke or period can be exactly regulated by adjusting the height of the upper part 'of the float. It

follows, however, that when the said part of the float is placed in a low position the portion of the chamber above it cannot be utilized, since during the period of inlet of liquid the said chamber can only be filled upto the upper part of the float, whereupon the pressure-valve is opened and the period of pressure begins. For this reason the free space existing above the liquid-level until shortly before the period of pressure begins must be iilled with compressed air before the forcing out of the liquid can. begin. The said space is therefore injurious with regard to the consumption of pressure and causes a greater consumption of pressure the smaller the quantity to be raised at each stroke. To remove this disadvantage, I have found that it is preferable to make the lower part of the float adjustable instead of the upper part` and to prevent expansive action by the pres.

sure agent, in consequence of the distance between the lower part of the oat and the end of the rising pipe, by causing an exhaustvalve to be opened by the descending float atthe same time as the compressed-air valve is closed. The buoyancy of the two parts of the float is so proportioned that it takes the buoyancy of both to open the pressuremedium-supply valve, but that ot' the lower one only to keep it open. valve allows the cut-od compressed air contained in the vessel to escape into the open air, so that the equalization of pressure need The said exhaust-v not take place through the rising pipe and liquid-conduits.

In the annexed drawing the apparatus is shown in vertical section.

The pressure-chamber 1 is connected by the pipe 2, controlled by an antireturn valve,

with the supply-pipe l of the liquid to be raised, the pipe 2 being connected in a suitable manner with thev pipe 8, leading to the tank.

The float in the receptacle 1 consists of a lower part 10 and an upper part 11, which are both rigidly attached to the rod 14, the lower float part 10 being adjustable upon the rod 14. Upon the latter two rings 30 and 31 are piveted, and betweenthese rings 30 31 the plate of the air-exhaust valve 26 ,is arranged slidably on the rod, the air-exhaust valve 26 being provided with a series of perforations, as indicated in section in the drawing. The compressed-air valve is not connected with the doat-rod 14 and is kept closed by its own vweight and the pressure of the pressure medium entering from pipe 6. The air-exhaust valve 26 shuts oft' the annular space and the tube '33, arranged for the exit of the air contained in the receptacle 1.

The apparatus operates Vin the following manner: The level of the liquid flowing in through the pipes 4- and 2 rises to the height of the upper part 11 of the float, so that the rod 14 is lifted by reason ofthe buoyancy of the oat l1 and carries along the lower ring 30, attached toit. This ring 30 thereby comes up against the air-exhaust valve 26, and the plate' of the latter shuts off the annular space V32 and the pipe 33 for the air-escape. after the air-exhaust is closed the pressuremedium valve 5 is opened by the rod 14 coniing up against'the latter and lifting it, so

that compressed air can enter the pressurechamber L through the ppe and the perforations of the air-exhaust valvev 26. The pressure medium now forces the liquid from the receptacle l through conduit 2 S to its place of consumption, and the pressdre-mediuni valve 5 is kept open by meansof the buoyancy of the lower lbat 1,0 till the level of liquid sinks so far as to allow the tloat 10 11 to gain overweight, when the float-rod 14E falling down releases the vamlve 5, which Just closes by gravity. Almost simultaneously, but a short moment later, the upper ring 3l on -the descending rod 1i pushes down the body 26 of the exhaust-valve and opens the latter, as shown in the drawing. During the then renewed inflow of liquid the eX- haust-valve allows the air in the vessel to escape through the annular space 32 and the tube 33 until the level of the liquid has risen so high as to cause the oat to ascend again, whereupon the operation is repeated.

What I claim is- 1. Apparatus for raisingliquids comprising in combination a chamber having inl-et for pressure iiuid and inlet and outlet for liquid, a pressure-valve controlling said inlet for pressure duid, a closing device therefor comprising a rod and a iioat attached to said rod and formed of two rigidly-connected bodies 10 and 11, the lower one of the said floatbodies being adjustable upon said rod and an air-exhaust valve for said chamber positively controlled by the float, said exhaust-Valve being closed by the upward movement of the float and opened by the downward movement of the oat, means for enabling the rod during its upward movement to iirst act upon the-pressure-medium Valve by its directthrust y previous to its action upon the air-exhaust Valve, and means for enabling said rod during its downward movement first to set free the pressure medium valve to allow it to close, and secondly to open the air-exhaust valve, substantially as set forth.

2. Apparatusforraisingliquidscomprising in combination, a chamber having inlet for pressure uid and inlet and outlet for liquid, a pressurevalve controlling said inlet for pressure iuid, a closing device therefor comprising a float formed of two bodies 10 and 11,and a rod connecting said bodies, the lower one of said float-bodies being adjustable upon said rod, and an air-exhaust valve for said chamber positively controlled by the float, said exhaust-valve comprising a valve-body 26 movably arranged between two adjustable collars 30 and 3l on the float-rod 14, which Y valve-body is pressed against and removed from its seat by the collars 30 and 31 respectively during the upward and downward movement of the rod 14 connected to the float 10 11, and a compressed-air valve 5 adapted to be opened by the direct thrust of the rod 14 after the air-exhaust valve is closed and adapted to b e closed before the air-exhaust valve is opened, substantially as set forth.

In witness whereof I have signed this specication in the presence of two witnesses.
